No output

Center Channel only plays

Muffled sound in L&R channels

Center channel sound muffled

No Input Level Meters

Check line cord to ensure good connection to the AC outlet and to the receptacle on the DC-2 rear panel. Check to make sure that the DC-2 rear panel power switch is ON.

Check the Status menu (under DISPLAY ADJUST: ON-SCREEN or FRONT PANEL menu Ñ or press and hold Record/Zone 2 on the remote and press OSD ON) to verify that audio is being received.

Check batteries to be certain that they are inserted correctly with proper polarity. Make sure that the infrared sensor on the DC-2 front panel is not obstructed. See "If all else fails..." on the following page.

Make sure that signal is coming into the DC-2. (Check the Status menu by pressing and holding Record/Zone 2 on the remote, then pressing OSD ON. This menu will display input level meters and sample rate, if applicable.)

Increase VOLUME using the remote control and check Front/Back and Left/Right BALANCE.

Check the DC-2 MUTE controls to make sure they are not engaged.

Check all other equipment settings and connections and verify that the amplifiers being fed by the DC-2 are operational.

Remember that the DC-2 mutes the output to any speakers which are not configured in the Setup menu. If speakers are added to (or removed from) your system, the Speaker Configuration menu must be altered accordingly.

Check to see if your HiFi VCR has dropped out of tracking Ñ readjust.

Your VCR Stereo/Mono/L-R switch may be in the wrong position Ñ set it to Stereo.

When no center channel is used, CENTER must be configured for NONE in the Setup Speaker Configuration menu.

The center channel amp may be connected to the subwoofer jack on the DC-2 rear panel. Reconnect to Center Output jack.

The meters will only appear when adjusting the Gain parameter of a selected, active input, or when the Status menu is displayed.

Make sure that video cables (particularly S-Video cables) are fully inserted and that the appropriate connector is assigned to the VIDEO IN parameter in the Input Configuration menu.
